General Texas Instruments High Voltage Evaluation (TI HV EVM) User Safety Guidelines General Texas Instruments High Voltage Evaluation (TI HV EVM) User Safety Guidelines WARNING Always follow TI’s set-up and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure your personal safety and those working around you. Contact TI’s Product Information Center http://support/ti./com for further information. Save all warnings and instructions for future reference. Failure to follow warnings and instructions may result in personal injury, property damage or death due to electrical shock and burn hazards. The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise and knowledge of electrical safety risks in development and application of high voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas Instruments. If you are not suitable qualified, you should immediately stop from further use of the HV EVM. 1. Work Area Safety: (a) Keep work area clean and orderly. (b) Qualified observer(s) must be present anytime circuits are energized. (c) Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages may be present, for the purpose of protecting inadvertent access I (d) All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other related apparatus used in a development environment exceeding 50Vrms/75VDC must be electrically located within a protected Emergency Power Off EPO protected power strip. (e) Use stable and non conductive work surface. (f) Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible. 2. Electrical Safety: As a precautionary measure, it is always a good engineering practice to assume that the entire EVM may have fully accessible and active high voltages. (a) De-energize the TI HV EVM and all its inputs, outputs and electrical loads before performing any electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely de-energized. (b) With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment hook-ups and other application needs, while still assuming the EVM circuit and measuring instruments are electrically live. (c) Once EVM readiness is complete, energize the EVM as intended. WARNING While the EVM is energized, never touch the EVM or its electrical circuits as they could be at high voltages capable of causing electrical shock hazard. 3. Personal Safety: (a) Wear personal protective equipment e.g. latex gloves or safety glasses with side shields or protect EVM in an adequate lucent plastic box with interlocks from accidental touch. Limitation for safe use: EVMs are not to be used as all or part of a production
